We're dividing 13549987 by 231 
Let's see how many times 231 fits into 13549987.

Going ahead to step 1:
If we divide 1 by 231, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 231

On to step 2:
The number 231 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 231

Going ahead to step 3:
The number 231 fits into 135 0 times, leaving a remainder of 135.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 135 and we're left with 135.
Bring next digit (4) of the dividend behind the 135 and repeat the process: 1354 / 231

Going ahead to step 4:
231 goes into 1354 5 times with a remainder of 199.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 1155 away from 1354, we end up with 199.
Take the next digit (9) from the dividend and append it to 199, then repeat: 1999 / 231

Step 5:
If we divide 1999 by 231, we get 8 and a remainder of 151.
Write down 8 as next digit of the result. 
Result so far: 58.0
The remainder is 151 after subtracting 1848 from 1999.
Take the next digit (9) from the dividend and append it to 151, then repeat: 1519 / 231

Step 6:
If we divide 1519 by 231, we get 6 and a remainder of 133.
Use 6 as the next digit of our solution. 
Result so far: 586.0
Subtracting 1386 from 1519 leaves us with 133.
Append the next digit (8) from the dividend to 133 and continue with: 1338 / 231

Going ahead to step 7:
1338 divided by 231 is 5 with a remainder of 183.
Use 5 as the next digit of our solution. 
Result so far: 5865.0
The remainder is 183 after subtracting 1155 from 1338.
Grab the next digit (7) from the dividend, add it to 183, then carry on: 1837 / 231

Going ahead to step 8:
If we divide 1837 by 231, we get 7 and a remainder of 220.
Write down 7 as next digit of the result. 
Result so far: 58657.0
Deduct 1617 from 1837 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 9:
When dividing 2200 by 231, we get 9 with a remainder of 121.
The next digit of our result is 9. 
Result so far: 58657.9
The remainder is 121 after subtracting 2079 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 10:
The number 231 fits into 1210 5 times, leaving a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 58657.95
Subtract 1155 from 1210 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 11:
231 goes into 550 2 times with a remainder of 88.
Write down 2 as next digit of the result. 
Result so far: 58657.952
Deduct 462 from 550 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 12:
880 divided by 231 is 3 with a remainder of 187.
Put 3 as the next digit of the answer. 
Result so far: 58657.9523
Subtract 693 from 880 to get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Let's proceed to step 13:
231 goes into 1870 8 times with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 58657.95238
If we subtract 1848 from 1870, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
231 can be fit into 220 0 times, resulting in a remainder of 220.
The number 0 becomes the next digit in our result. 
Result so far: 58657.95238
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 15:
2200 divided by 231 is 9 with a remainder of 121.
The next digit of our result is 9. 
Result so far: 58657.9523809
If we take 2079 away from 2200, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Going ahead to step 16:
231 goes into 1210 5 times with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 58657.95238095
If we take 1155 away from 1210, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Our division results in 58657.95238095 with a remaining 5.5e-08.
